摘　　要：为了获取许昌市郊区土壤中铜的含量,以许昌市郊区不同区域蔬菜大棚土壤为研究对象,用网格法从大棚中采集土壤样品.将样品消解获得样液,采用电位滴定法进行测定.结果表明,清泥河或清潩河地区土壤中铜的含量高于标准值,其他区域符合国家标准.该法具有准确度高、重现性好、操作简便快速的特点.In order to obtain the copper content in the soil of the suburbs of Xuchang,the soil samples of the greenhouses in different areas were taken.By the grid method,the samples were digested to obtain the sample solution,which was determined by the potentiometric titration method.The results show that the content of copper in the soil of Qingni or Qinglu River is higher than the standard value,while other regions meet the national standards.This method has high accuracy,good reproducibility,simple and fast operation.
